Project overview

About the Project

Lake Hawkeye Data is a modern research and technology hub located on the former Cayuga Power Plant site. The project revitalizes a long-standing industrial property — once dedicated to utility-scale energy production — and transforms it into a center for advanced digital processing and research innovation.

The site’s industrial zoning and historical use align naturally with redevelopment, allowing for an efficient transition that minimizes new land disturbance while maximizing the value of existing infrastructure. This approach supports responsible community development by repurposing established assets rather than expanding into undeveloped areas.

Project Highlights

  • Redevelopment of a legacy industrial site, with phased development in parallel with infrastructure readiness:

    • ~80 acres initial development

    • 3-5 data center buildings

    • ~300 MW of total capacity at full buildout

    The site houses existing transmission interconnection and substation infrastructure, and its industrial zoning and historic use are aligned with proposed redevelopment.

  • Located in Central NY, where grid electricity is predominantly zero-carbon and substantial surplus power is available.

  • Meaningful construction jobs expected during buildout as well as permanent skilled positions once operational.

  • Phased development approach:

    • Phase I: Three buildings totaling ~150 MW

    • Phase II: One to two additional buildings, up to ~300 MW total

  • Millions in new property tax revenue expected, plus an annual community fund to support schools, parks, and local initiatives.

    New York’s Just Transition Working Group has identified former coal plant sites like Cayuga as ideal for reuse, particularly for data centers that bring jobs, investment, and tax growth.

  • Designed for long-term (10+ years) hosting agreements with leading global technology companies.

DESIGNED WITH THE COMMUNITY IN MIND

Responsible Development

  • Water for data center operations will be supplied by the Bolton Point system and supported by on-site storage. Existing Cayuga Lake intake structure is not required for data center operations.

  • Advanced cooling technology keeps sound levels well within local limits, ensuring minimal impact at the residential property boundary.

  • Incorporates LED lighting, demand-response capability, and potential integration with adjacent planned solar and battery storage projects.

    The data campus project is subject to SEQR and comprehensive environmental review, as well as ongoing coordination with the Town of Lansing, NYSDEC, and USACE.

  • Converts a long-idle industrial property into productive use, aligning with state clean energy and economic development goals while minimizing new land disturbance.

  • As part of the site’s transformation, TeraWulf plans to demolish the former power plant stack at Cayuga, a visible step toward retiring legacy infrastructure and transitioning the property for modern use.
